  • What is the ITF World Tennis Number?

    The WTN is a global rating scale that allows tennis players to find the right playing partner or program. It is a scale between 40 and 1, with 40 being a beginner player and 1 being an elite professional. This scale is for all players, regardless of age, gender, or ability. Players will have a separate WTN for both singles and doubles.

  • Why is the WTN important?

    The WTN is a global initiative led by the ITF to bring the tennis community together. The WTN will allow tennis players across the globe to find the right person to play with and the right program to join. This enables level-based play to ensure everyone is enjoying the sport. The WTN initiative is a massive opportunity for tennis federations across the world to grow and unify tennis together.

  • How is the WTN calculated?

    The WTN algorithm uses match results provided by national tennis federations to calculate ratings for players. Some key principles of the WTN algorithm include:

    • Current match results carry more weight than older results.

    • Sanctioned competition results carry more weight than club/recreational results.

    • Match results are analyzed at the set level; the algorithm takes into account each individual set as its own result.

  • Where can I find my WTN?

    Competitors registered with their respective Provincial/Territorial Tennis Association will be able to find their WTN their profile page via the national-provincial match play platform. The system will need 6 match results to calculate an accurate WTN.

    Registered Canadian competitors will also be able to find their WTN on the global WTN site developed by the ITF. The global WTN site includes special features for tennis players.
